When performing the gram stain, the Crystal Violet solution is composed of 20 mL of 95% ethanol in a final volume of 100 mL. If only 70% ethanol is available, how many mL of ethanol should be added to achieve a final volume of 1,000? Report your answer to 2 decimal places. Perform all calculations in a single step using Excel to avoid accumulated rounding error.

(When answering this problem, report the answer with the appropriate number of significant figures. When entering units, use proper abbreviated units with proper capitalization.)A beverage drink mix sample is prepared by mixing a packet of beverage powder in a gallon (3.78 L) of water. A sample for analysis is prepared by diluting 10.00 mL of this solution in a 50.0 mL volumetric flask. A student calculates that the concentration of dye in the analyzed beverage mix solution is (2.59x10^-5) mol/L. Determine the mass (in grams) of food dye in the beverage mix packet. Hint: The answer is assumed to be reduced to the highest power possible.
please see image attached: A chemistry student weighs out 0.146 g of chloroacetic acid into a 250. mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.1400M(molarity) NaOH solution. Calculate the volume of NaOH solution the student will need to add to reach the equivalence point. Round your answer to 3 significant digits.
If 10.0 mL of a 3.00 M H2SO4 stock solution are diluted with water to a final volume of 0.500 L, what will be the final concentration of H2SO4 in the dilute solution? Report your result in decimal notation and to the proper number of significant figures. All numbers are measured. a) 0.0300 Mb) 0.300 Mc) 0.150 Md) 0.0600 Me) 0.600 M
A student dissolves a Jefferson nickel to make 100.00 mL of solution in a volumetric flask. The student takes a 5.00 mL aliquot of the first solution and dilutes it to make 100.00 mL of a second solution. The student places a sample of the second solution in a cuvette for analysis using spectrophotometry. The molarity of the copper solution in the cuvette was determined by spectrophotometric analysis to be 2.90×10−2 M Cu. Calculate the mass of copper in the Jefferson nickel used to make the first solution.
The protocol for a given lab experiment specifies that you should prepare a diluted solution by combining 1.0 mL of a stock solution (one that is more concentrated) and 9.0 mL of deionized water. Which piece(s) of laboratory equipment should you use to carry out the dilution? A. 10 mL volumetric pipet B. 1 mL volumetric pipet C. 10 mL graduated cylinder and a 2 mL serological pipet D. 10 mL seological pipet E. 10 mL graduated cylinder NOTE: the answer is not 10 mL volumetric pipet nor is it 1 mL volumetric pipet.
This is my 2nd attempt to receive help with this problem. The previous expert confused me by saying the answer is less than 109.5? Does that mean it should be 90? Please provide clarity instead of adding confusion; otherwise the payer loses a question for assistance. Thank you.
Part 1 – Preparation of CaCO3(s) The following is a procedure that was theoretically performed by a student. Read through the procedure and answer the questions below. A 10.0 mL graduated cylinder to measure 10.0 mL of a 1.00 M CaCl2 solution into an initially empty 50.0 mL beaker. A 50.0 mL graduated cylinder was then used to measure out 25.0 mL of 0.500 M K2CO3. This K2CO3 solution was then added to the beaker containing the CaCl2 The solution became cloudy, and the student concluded that a precipitate must have formed. Write a balanced chemical reaction below, including phases, and identify the chemical formula of the precipitate: Answer the questions below as part of Data Analysis. 1. What is the actual yield of the product? 2. Using stoichiometry, calculate the limiting reactant, and the theoretical yield (the mass of CaCO3 product) for the reaction. 3. Determine the percent yield of the reaction.
Based on the data in the figure below, knowing that the nominal volumes of the flask, pipette and burette are 100 mL, 10 mL and 12.5 mL (half the volume of the burette) respectively, answer: What is the most accurate volumetric instrument? Show calculations and be careful with scales

The concentration of PSA (prostate-specific antigen) in the blood is sometimes used as a screening test for possible prostate cancer in men. The value is normally reported as the number of nanograms of PSA per milliliter of blood. A PSA concentration of 1.7 ng/mL1.7 ng/mL is considered low. Express that value in terms of the units shown. PSA= g/L PSA= kg/m3 PSA= mg/L
